I'm going to halfway copy Trollheart and choose a Red Dwarf cast member, but I'm going with
Kryten instead. His defeatist attitude and dorky mannerisms are hilarious, but he's also very lovable.
Ellen Ripley from the Alien movies. I've loved strong women my entire life and watching Alien at a pretty young age had a lot to do with that. I used to play Alien with my Gi-Joe toys all the time and pretended that rows of trees were the Nostromo when I was playing outside.
Sioban from the 4 part comic book
Complainte des Landes Perdues. She's a young princess who practises sword fighting in secret and has a strong moral compass. A witch eventually clouds her mind and has her fall in love with a diabolical prince and everyone in the kingdom loses faith in her and wants her dead. Stuff happens, and the day is saved. Damn, I really want someone to make a movie based on these comics. Lot's of celtic mythology and devil worshipping.
